无规位相板在实现靶面均匀辐照方面的性能分析
Analysis on Performances of Random Phase Plate in Realization of Uniform Irradiation on Target Plane
无规位相板 均匀辐照 光强分布 复杂波面 random phase plate uniform irradiation intensity distribution complicated wave-front
摘要
数值分析的结果表明:尽管实际辐照靶面的激光光束其振幅和位相是涨落变化的,但是,使用无规位相板同样能改善光束辐照靶面的均匀化程度;无规位相板取不同的无规位相分布对靶面辐照均匀化的影响较小。还讨论了靶面离焦时其光强分布的变化情况。
Abstract
The results of numerical analysis show that the uniformity of illumination of laser fusion target can be improved by using a random phase plate (RPP), though the magnitude and phase of laser beams irradiating the target plane are practically fluctuated. Any random phase distribution of the random phase plate has less effects on the unformity of laser irradiation on the target plane. Besides, the intensity distributions of the target plane defocused are discussed.
